, we proceed to perform all operations described on statement:![R'(x,y) = O(x,y) + k\cdot [R(x,y)-O(x,y)]](/tpl/images/1019/0820/7a0a9.png)
 (1)
- Point of reference.
- Original point.
- Dilated point.
- Scale factor.
, 
, then the dilated point is:![R'(x,y) = (0,0) +3\cdot [(1,2)-(0,0)]](/tpl/images/1019/0820/6e1da.png)
(2)
- Translation point.
- Translated point.
, then the translated vector is:
